Abstract The traditional approach for the beneficiation of South African siliceous sedimentary phosphate ores has been reverse cationic flotation. robustness this approach, however, a concern due to its sensitivity parameters such as slimes content, headgrade (P 2 O 5 and SiO content), reagent dosages conditioning times. mineralisation ore body under investigation is predominantly carbonate flu...

A suitable grinding fineness and flow-sheet could potentially reduce the mechanical entrainment of gangue minerals in the flotation process of microcrystalline graphite. In this study, the suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and laboratory grind-flotation tests. The target grind size of this ore should be 92% passing 74 μm based on the mi...

Titanium is a very important element for several industrial applications, being one of the ninth most abundant elements in the Earth’s crust (0.63% wt). In this work it will discuss the different mining and industrial activities involved in the production of titanium dioxide. The first step analyzed will treat about the beneficiation mining process of titanium mineral, and secondly, it will dis...

The article presents the results of research on development processes and equipment for ore preparation pneumatic dry beneficiation mineral ores. methods crushing grinding before enrichment minerals have been considered, geomaterials is investigated. Highly efficient prototypes are developed tested: crushers multiple dynamic impact RD-MDV-900, DKD-300, centrifugal grinders CMVU-800 VCI-12, sepa...
